I wonder, wherever this writer found this 100km/hr story. A metro train is not a long-distance one and the line has many stations within about @2 km which is not good for speed driving.
There is no reason to believe the speed will be 100 km/hr. The average speed will be about 40km/hr if one divides the total distance by total time.
China exports driverless metro to Istanbul, 120km/h speed class fully automated and driverless.
Istanbul’s Newest Driverless Metro Train Is Headed Home from China
The future of train travel continues to reach new heights in Istanbul, Turkey. After the country placed an order for a new driverless train six months ago,
CRRC Zhuzhou Electric Locomotive in China developed and finished production. The new train is part of an ongoing metro project that started in 2014 and opened in 2018.
Turkey followed the lead of numerous other countries in
Europe and Asia that are moving toward more fully automated metro lines, which often mean additional capacity, the use of less power and increased running capacity.
As established by the International Association of Public Transport (UITP), the train has been graded as a GoA 4, meaning that it has fully automated features. This
smart train uses technologies from Thales, which includes the latest 5G technologies, remote tracking, real-time data, intelligent lighting, and touch-screen control panels. Although a surveillance driver will be stationed on the train, GoA 4 trains autonomously start and stop, as well as open and close doors, detect obstacles, and react to emergencies.​

The new train is the first that CRRC has exported overseas. It was designed to travel 120 kmh (74.5 mph) and includes four carriages with the capacity for 1,100 passengers. Similar to other trains produced by CRRC, it has an aluminum alloy articulated car body and an energy-absorbing anti-collision design to enhance safety, as well as other innovative features.
This train will be the first of 176 of its kind to hit the Istanbul rails. The line it will operate on will enable a 35-minute journey from Gayrettepe to the airport. While most of the tunnel work is completed, the completed project isn’t set to open until 2022. The hope is to have the first line in operation by August 2021. When completed, the new lines will serve 700,000 passengers a day.
Along with providing Turkey a newly designed train set, CRRC has acquired a contract with Ukraine to manufacture eight five-car transits to be completed by 2022. The trains will travel 80 kmh (49 mph) and be approximately 96 meters (317 feet) long.
The company also unveiled its next Type B generation design at the recent World Intelligence Congress in Tianjin. Its stainless steel construction is 10 percent lighter than previous designs and features permanent magnet traction, resulting in potentially significant cost savings. It will be able to carry 2,300 passengers.
